Quizplus · Accepted Answer

The edge effect in a forest fragment typically affects the outer 100 meters. The area affected by the edge effect can be calculated by subtracting the unaffected inner area (400 m × 400 m) from the total area (600 m × 600 m). The fraction of the fragment experiencing decreased relative humidity is (600^2 - 400^2) / 600^2 = 5/9.
